FUMIGATOR.

SPECIFICATION forming part of Letters Patent No. 430,018, dated June 10, 1890.

Application iled January 31, 1890. Serial No. 338,713. (No model.)

To LLZZ whom it nuty concern.'

Be it known that I, CALVIN Q. HAYES, of Goldeld, in the county of Vright and State of Iowa, have invented certain new and useful Improvements in Fumigators; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in fumigators; and it consists in the combination of a cylinder or chamber in which the fire is made, an outside cylinder, which is separated a suitable distance therefrom at every point except its upper end to prevent it from becoming heated, a conical perforated cover placed inside of the top of t-he firechamber, a valved cylinder, which is used to force the products of combustion into the animals burrow, and a suitable packing, asl

will be more fully described hereinafter.

The object of my invention is to provide a fumigator by means of which poisonousfumes can be forced into an animals burrow, and in which the parts are so constructed and arranged that the cylinder upon which the packing is placed and has a sliding or rolling movement never becomes so heated as to injure the packing.

The accompanying drawing represents a vertical drawing of a fumigator which ernbodies my invention.

A represents a cylinder or fire-chamber, which is made conical in form, and which has its lower end contracted, as shown, so as to adapt it to be inserted into the upper end of an animals burrow. Secured to one side of the lower end of this cylinder is a foot-support B, by means of which the fire-chamber is held in position while in use. In this chamber is built a fire, upon which are placed the poisonous substances of any kind for the purpose of producing poisonous fumes or vapors which will destroy animal or insect life. After the re has been built in this chamber there is placed in its upper end a conical perforated cap or cover C, which serves to prevent the fire from being drawn or sucked out of the chamber A while the fumigator is being operated, but which does not interfere with the free downward passage of the air to the tire. Secured rigidly to the upper end of this vertical chamber A is the cylinder D, which has straight sides and which does not come in contact with the chamber A at any other point than its upper end. These two cylinders being separat-ed, as shown, and the space between them communicating with the outer air at the lower end ot the cylinder D, the cylinder D is always kept cool, so that the packing G, which is placed around it, does not become injured by the heat.

Passing down over the upper end of the firechamber A, the cylinder D, and the packing is the operating-cylinder I, which serves as a piston or plunger to force air down through the re into the fire -chalnber, and which makes a tight joint with the packing G. As this cylinder is worked up and down over the cylinder D, the packing, of any suitable construction or material, has a rolling or sliding movement over the outer surface of the cylinder D, so as to correspond to the motion ofthe cylinder I. This packing being made round to adapt the packing to Iroll between the two cylinders D and I, it is not worn out as rapidly as it would be if it remained stationary, nor could such a long movement of the cylinder I be so readily given. In the upper end of the cylinder I is formed an airopening J, and this opening .I is controlled by the valve L, which is placed inside of the cylinder and adapted to open inwardly. This cylinder I is provided with suitable handles, by means of which the cylinder can be operated and the fumigator carried around.

Then the cylinder I is worked up and down, the valve opens at each upward stroke, so as to admit air, and then closes as the downward stroke begins, and thus forces the air through perforated cap or opening and through the cylinder, thus forcing the deadly fumes directly into the burrow for t-he purpose of destroying burrowing animals of all kinds.

This fumigator is very light, cheap, simple in construction, aud especially adapted for the destruction of ground-hogs, prairie-dogs, and destructiveburrowing animals or insects of every kind.

IOO

All sorts of poisonous substances or eomponnds may be placed in the fire so as to produce Jshe fumes or vapors which are to destroy animal or insect life.

Having,` thus described my invention, I

5 claim- The combination 01 the cylinder in which the fire is made, Jche cylinder D, which is secured thereto ab its upper end and which is separated therefrom by means of an air- Io chamber, the packing G, placed around the cylinder D, and the Valved chamber or cyl inder I, which forms a tight joint with Jhe packing, substantially as shown and described.

In testimony whereof I afx my signature in presence of two Witnesses.
